must safety backup on abseil.
Use with a fall arrest harness (fig. 8.1):
1) Pulling on the engaged side of the rope, the cam must
lock the device: in case it doesn't, check the correct in-
sertion of the rope.
2) Load progressively your weight on the device, hold-
ing the free-end of the rope: The cam must lock on to the
rope. If the cam locks on to the rope, the device is work-
ing properly and is ready to use. If the Cam doesn't lock
the device, check whether the rope has been correctly in-
serted, if the device still doesn't lock on to the rope, re-
move it from further use immediately.
Use on an anchor point (fig. 8.2):
1) Remember to pull the free end of the rope through the
snapping catch.
2) Pulling on the engaged side of the rope, the cam must
lock on to the rope. If the Cam doesn't lock the device,
check whether the rope has been correctly inserted, if the
device still doesn't lock on to the rope, remove it from fur-
ther use immediately.

The Sparrow descender is a Personal Protective Equip-
ment (PPE) intended to be incorporated in a rope access
system. Rope length adjusters must not be used for fall ar-
rest. Max work load 150kg. The Sparrow descender is
a rope length adjuster type C intended for descending a
rope (anchor line). An anchor line loaded with the entire
weight of the user, has to be considered a work line and
is not meant to arrest a fall. It is mandatory to use a fall
arrest back-up device type A connected to a safety line.
Pay attention that the back-up system is never loaded on
to the work line.
Abseil of one person (fig. 9).
Holding the free end of the rope, gradually pull on the
control handle to adjust the speed. For difficult abseils,
requiring a stronger brake power, insert the free end of
the rope through the snapping catch in order to have a
better control over the heavy weight and gradually pull on
the control handle to adjust the speed. Attention! Always
hold the free end of the rope whilst abseiling. To stop the
descent, let the control handle go: The lever will sponta-
neously return to "REST" mode. No further maneuvers are
required to up-keep the position hands free. For avoiding
any interfering with the handle or to work more comforta-
bly, it's possible to shift the control handle on to "STAND
BY" mode. Attention! Never lose governance over your
abseil, it may result difficult to regain control.
EBS (Extraordinay breaking system).
EBS is security systems that decreases the speed rath-
er than increase it, when the lever is accidentally pulled
downwards. This maneuver has to be used only in case
of emergency and not during normal employment. Reg-
ular use of this safety system may lead to a faster wear of
the rope.To resume the descent, firmly hold the free end
of the rope and gradually release the control handle back

in to the "REST" position. At this stage you can re-start de-
scending following the instruction above.
Warnings.
Always wear a pair of good suitable gloves to protect your
hands when manoeuvring the device and the rope (we
suggest the use of 7X980 gloves employed to carry out
the certification test); Use only static or semi-static rope
(core + sheath) between 10.5 and 11 mm certified to EN
1891 type A (For the certification of this device, the fol-
lowing ropes have been employed: Teufelberger Patron ø
10.5 mm e Patron PLUS ø 11 mm); There are restrictions
for the length or slant of sloped pathways. No special pre-
cautions are required when accessing sloped trails; Any
overloading or loading on the device can harm the an-
chor line; Never use lanyards or extensions of any mean
to connect the device to your harness; During use, the an-
chor point must always be placed above the waist belt
attachment point of your harness; The technical perfor-
mances of the anchor line might vary considerably, due to
dirt, moisture, ice, repeated descents on the same stretch:
keep in mind that these variances will influence the be-
havior of the rope inside the device, and consequently,
the speed of descent.
EN 341:2011
The Sparrow descender can be employed in rescue op-
erations. Maximum allowed descend: 100 m; work load:
30÷150 kg.
Descent from an anchor point (fig. 10-11).
Insert the free end of the rope through the snapping
catch; hold the free end of the rope gently push up the
control lever to release the rope gradually. To adjust the
speed, vary the hold over the free end of the rope. To stop
the descent, let the control handle go: The lever will spon-
taneously return to "REST" mode. No further maneuvers
are required to up-keep the position hands free. Atten-
tion! Always hold thight the free end of the rope whilst
lowering the load. When you are lowering a light weight
(30-50 kg) and you have difficulties feeding the rope
(rope might be dirty, wet of too stiff), you can release the
rope from the snapping catch, advance the hand hold-
ing the free end of the rope to control the speed. Atten-
tion! Pay attention that the hand holding the free end of
the rope doesn't get too close to the device. Attention!
Never lose governance over your abseil, it may result dif-
ficult to regain control.
EBS (Extraordinay breaking system).
EBS is security systems that decreases the speed rath-
er than increase it, when the lever is accidentally pulled
downwards. This maneuver has to be used only in case of
emergency and not during normal employment. Regular
use of this safety system may lead to a faster wear of the
rope. To resume the descent, firmly hold the free end of
the rope and gradually release the control handle back in
to the "REST" position; At this stage you can re-start de-
scending following the instruction above.
